Two posters, two presenters, one conference

Andrzej Jankowski and Ivan Flammia’s posters selected for oral presentation at the ESOF/Marie-Curie Conference 2012

Andrzej Jankowski and Ivan Flammia, currently enrolled as PhD researchers at the Institute of Optoelectronics at University of Duisburg-Essen, have participated this year in the Marie Curie Actions Conference 2012, as part of the Euro Science Open Forum convention (10th -15th July, Dublin).

As members of the Marie-Curie Initial Training Network MITEPHO (Microwave and Terahertz Photonics), the two researchers had the chance to attend seminars dedicated to the development of soft-skills (such as preparation of project proposals, patent application, communication with non-scientific audience) as well as lectures and talks given by Nobel’s prize laureates, leading researches, policy makers and business leaders.

Andrzej and Ivan took part in a special digital poster session, focusing on different science fields (chemistry, environment and geosciences, engineering, information and computer science, life sciences, physics and mathematics, social sciences and humanities), with emphasis on the communication of scientific results to non-scientific audience. Among the numerous participants in the poster session (a total of 120 posters were submitted) only 20 were selected to give an oral presentation, on the basis of the following criteria: “creativity, accessibility to non-scientific community and quality of results”. Andrzej and Ivan were both chosen by a panel of experts for the engineering category and presented the work they have carried out in the Center of Optoelectronics in the past months.

Andrzej’s poster, entitled “Antenna-integrated THz photodiodes”, presented a new concept of a small-scale integrated photonic THz transmitter featuring a log-periodic toothed (LPT) antenna integrated with a passive waveguide-coupled p-i-n photodiode. This device is designed to work in a specific region of the frequency spectrum called the THz region (from 30 GHz up to 3 THz). Such a transmitter can find application not only in the telecommunication industry, radio astronomy or spectroscopy, but also in safe and security systems. The presentation furthermore included information about the packaging of the devices and experimental validation of the produced devices.

Ivan presented a poster entitled “Quasi-Hermetic Photonic Transmitter with WR12-Output for Radio-over-Fibre Applications”, where a new photonic transmitter for E-Band (60-90 GHz) Radio-over-Fibre systems was introduced. The developed concept allows for low-cost integration of optical components (photodiodes) and radiofrequency elements (high-gain horn antenna) and introduces the possibility of cost-effective hermetic packaging without the need of sealing plates or radomes. Ivan presented examples of applications and reported simulations and experimental characterization of the photonic transmitter’s prototype as well as successful back-to-back 1 Gb/s error-free data transmission.
